who says tech cannot have any magic? i discovered this bug. it was very weird, but i think it is useful.
this is how it happed: worker has mining for gold. while he was mining, i send him to harvest wood. he supposed to finish mining, take gold to castle and then go harvesting. but he didn't finish mining.
look this:

Load: 357 Gold :?: :?:
i went to battle after that. i didn't see what happed, but he stopped and toked to castle.
